Abstract

The fixation arrangement of the present invention is applied to a compressor of the type which comprises a shell (1) inferiorly defining an oil sump (3) and housing: a crankshaft (4) journalled in a cylinder block (2) and carrying a rotor (6) formed by a stack of annular laminations; and an oil pump (10) comprising a tubular sleeve (20), which is superiorly mounted to the rotor (6) and inferiorly immersed in the oil sump (3), and a pump shaft (30). The fixation arrangement comprises at least one retention element (40) radially and axially locked around the tubular sleeve (20) and having a radially outer locking portion (41), which is seated and radially forced against a respective confronting circumferential extension (6c) defined between two consecutive annular laminations, in order to axially lock the tubular sleeve (20) to the rotor (6).
